With military helicopters flying above her southeast Houston neighborhood, Frances Jerrals didn’t know what to think.

“When you see this, you think the worst. When you hear this, you think the worst,” Jerrals said.

And so, she passed along her concern.

“She told me ‘don’t come home it sounds like we’re in a war zone. Guns, shooting, helicopters flying around the house,'” Isaac Robertson Jr. said.

The U.S. Army along with other agencies took over the old Carnegie Vanguard High School near Scott and Airport. There were armed men in fatigues, plenty of weapons and what many thought were real live rounds

“I felt like I was in a warzone.” Jerrals said. “It was nonstop. I was terrified.”

Turns out, it was a multi-agency training drill that Jerrals wished would have come with warning.

“They could have done a better job in notifying the neighborhood,” Jerrals said.

The Army did not give any details of what the training is for. Some people we spoke to needed no explanation.

“If it’s to protect our kids, I’m all for it,” neighbor Glenn DeWitt said. (That’s right just forget about the Posse Comitatus Act that prohibits military from doing law enforcement in the States)
